Description

Technical Field

[0001] The utility model specifically relates to an audio transmission audio PCBA board, belonging to the technical field of PCBA boards. Background Art

[0002] PCBA, or printed circuit board assembly, refers to the process of assembling electronic components and PCBs. In PCBAs, electronic components—such as chips, resistors, and capacitors—are secured to the PCB through soldering and mounting. PCBAs are more complex and critical than PCBs, determining the performance and quality of electronic devices. Similarly, in the audio and sound industry, PCBAs are core components of various audio transmission systems. By assembling and soldering these components together, the proper functioning of the speakers is ensured.

[0003] For example, the Chinese authorized utility model patent with announcement number: CN219107755U, an audio transmission audio PCBA board, including a PCBA board body, a structural part is provided on the top of the PCBA board body, a USB interface is embedded on the top of the PCBA board body on one side of the structural part, a connector is provided on the top of the PCBA board body, and a protective component is detachably connected to the top of the PCBA board body; the protective component includes a snap-fit ​​frame, a protective top plate, and a connecting side column; two connecting side columns are divided in parallel, and multiple protective top plates are horizontally arranged between the two connecting side columns, and the snap-fit ​​frame is located at the bottom end of the end of the connecting side column; the top of the PCBA board body can be quickly installed with a protective top plate and a connecting side column, which can protect the entire PCBA board body, reduce the impact of multiple components on the top of the PCBA board body, and will not affect the normal connection of multiple components with the equipment. The protective top plate can be moved horizontally according to usage requirements.

[0004] This utility model is fully functional and can meet most usage situations, but it still has some shortcomings.

Under the condition of uniform heat dissipation, this utility model may not only have insufficient heat dissipation, but may also have a situation where the temperature at most locations is normal but the temperature at the core point is difficult to control; at the same time, the current cannot be stabilized during daily use. If there is a peak in electricity consumption in summer or winter, voltage fluctuations may occur. If these fluctuations are not handled, the service life of the PCBA board will be shortened.
